MCP security gateway architecture that authenticates tool calls, routes execution into isolated sandboxes, sanitizes responses, and returns clean results to the AI agent.

Microservices API Gateway Architecture

A microservices API gateway architecture diagram showing request routing, JWT authentication, rate limiting, service discovery, and response aggregation across distributed backend services. This template models the entry point for all client traffic in a microservices ecosystem, enforcing security policies before requests reach internal services. Ideal for platform engineers designing scalable API infrastructure with centralized cross-cutting concerns.

Microservices Service Mesh Architecture

A service mesh architecture diagram with Istio or Linkerd sidecar proxies handling mTLS encryption, traffic policies, circuit breaking, and distributed tracing across microservices. This template visualizes how a service mesh abstracts networking concerns away from application code, enabling zero-trust communication between services. Essential for teams adopting service mesh infrastructure to improve observability and security.
